Rose Byrne was pregnant with her son Rocco when filming this movie.

Airbags don't explode when you jump on them.

Certain scenes that were in the movie are different on blu ray. Like there's a shot where the main three girls are sitting side-by-side while Chloe smokes a joint looking wide-eyed. That shot is in the movie, but it's part of a video they upload to get members interested... so you see it from the POV of someone watching a YouTube video. The scene where the girl goes through the windshield is in there, but oddly her flying past Seth Rogen in slow motion is not. It just cuts to him hitting the brakes and her flying past the car on to the ground. In the scene where Zac Efron says he's going to dance for the girls, the part where Ike (in clown make up) says "You want me to go up with you?" - that last part isn't in there.
